and useful Improvements in Headlights for.

Bicycles, Magnetic Drive, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the ac companying drawings, and to numerals of reference marked .thereon, forming apart of this specification. V

This invention relates to improvements in a combination head-light and horn, designed for use in connection with bicycles, motor-' cycles and for other analogous uses and purposes for which it may be adapted.

The principal object of this invention is the provision of a combined head-light and horn of the character specified, wherein there is provided a magneto as the source of energy for causingthe lamp to glow, the parts being so constructed and arranged that the shaft for actuating the magneto acquires its rotary motion from a ground wheel of the bicycle or motor-cycle and is employed as the mstrumentality through which to effect the sounding of the horn when desired.

The invention is also concerned with the provision of a simple casing for housing the working parts, and to which the head-light and horn may' be attached; and also with the provision of simple means by which to adjustably support the asing on ajframe part of the bicycle or motor-cycle.

Other objects and advantages will appear in the following specification, and the invention will be particularly defined in the claims hereto appended.

In the accompanying drawings, forming a part of this specification, Figure 1 represents in lan a central horizontal sectional view of t e structure, taken on line 1-1 of Fi 2.

igure 2 is a side elevational view of the structure, illustrated in connection with a fragmentary portion of a ground wheel and its steering fork. r

Fig. 3 is an elevational view and section 1 taken on the line 33 of Figure 1.-

suitable manner to the 1.. tached to a sleeve or designed to engage In Figs. 1 and 2 of the accompanying drawings, I illustrate my improvements in connection with a fragment of a front ground wheel of a bicycle, and also in connection with a rigid frame part 6 representing a fragment of the usual steering fork for the same, the ground wheel being equipped with the usual pneumatic tire 7.

As a means of operatively'supporting my improvements, I rovide a pair of clamping plates 8, to em race the part 6, connected at one end by the bolt and nut structures 9 and 10, respectively, and at the other end by the bolt and wing-nut structures 11 and 12, respectively. Engaged on the bolt 11, between the clamps 8, is the reduced end 13 of an angplar bracket 14, which is cast with a drum s aped casing consisting of a circular plate 15 having a rim flange 16, the edge of the rim flange being cast with enlarged internal lugs 17 tapped as at 18 to receive the screws 19 of a circular closure plate 20. The plate 15' is-preferably cast with a central outwardly projecting hub'21, bored to provide a bearing for a rotatable shaft 22, on the outer end of which is tightly secured a drive wheel 23, designed to have frictional engagement with the tread of the pneumatic tire 7. :The drive wheel 23 is carried between a collar. 24 and washer 25, the latter being held in position by a nut '26 threaded on the end of theshaft. The shaft 22 also has bearing in a bar 27- (Figs."

1 and 3) which spans the interior diameterof the casing and which has its opposite ends bent over and which ma be secured in any 27 has a central extension 28 on one edge, to which is secured by screws 29 an angle bracket 30, in which the end of the shaft 22 rotates.

' Attached rigidly to the shaft 22, adjacent the side plate 15, is a formed with branches 32, between which are a series of coil-wound armatures 33, at-' guardj34 surrounding the shaft 22, and supported by a ring 35, which is secured by screws 36 to the-plate 27., Oneend 37 of the winding connects with a binding post 38, and the other end with an armature 33. The binding post 38 is arranged in a block of insulation 39, secured in the side late 20. To the post 38 is attached aswitc 40 having a contact 41, a. binding post 42, held ange 16. Said bar permanent magnet 31,

in an insulation plate 43, also set in the mit the inward projection of the lamp terminal for this purpose.

The incandescent lamp 50 is carried in a socket 52, formed centrally of a reflector 53 which is set in a hood 54, flanged to encompass the opening 51 and to besecured to the flange 16. The outer end of the hood as well as the reflector is closed by a lens 55. In the present embodiment, the electric return is effected through the lamp base, reflector, hood and casing. From this construction, it will be obvious that when the ground wheel is rotated, the magnet 31 Wlll be spun around the armatures setting up a current and causing the lamp to glow.

When it is not desired to. light the lamp, the circuit is broken by disengaging the switch 40 from the binding post 42.

Cut in the;plate 20, eccentrically with respect to the shaft 22, is an opening 58, which is closed by a vibratory membrane 59 that 1s secured together with the horn 60 to the plate 20 by means of the bolt and nut structures 61 and 62, respectively. Attached to the membrane 59, centrally thereof, 'is a conical stud 63, designed to be engaged by teethv formed on the adjacent side of the wheel 64, which is slidably mounted on and driven by the shaft 22 and normally held out of engagement with the stud 63 by a spring 65, interposed for the dpurpose between the angular bracket 30 an said wheel. The spring 65 also normally holds the wheel 64 against the forked end 66 of a bell-cranklever 67, pivoted at 68 between the lugs 69,

cast on the flange 16. This whole arrange-' ment is such that when the shaft 22 is rotated and the bell-crank-lever 67 is tilted on its pivot to move the wheel 64 towards the horn, the teeth of said wheel will successively impinge the'stud 63 causing the membrane to vibrate and consequently sounding the horn.

The bell-crank-lever has a flattened end 70, in contact with a cap 71 secured on the end of a twisted wire strand 72, which extends outwardly throu h an opening 7 3 and into a housing 74 (%i 4), where it is secured to the disk-shaped use 75 of a pushbutton 76. Coiled around the wire 72 within the housing 74 is a compression spring 77, which normally urges the button into outward position, but which yields under pressure exerted on the button to cause the cap 71 to impinge the bell-crank-lever.

which co-operates another clamping member 82 as a means of securing the housing on the handle-bar (not shown) of the bicycle. The

two clamping members 81 and 82 are drawn together and tightened on the handle-bar'by means of the bolts and nuts 83 and 84,respectively. V p

Through theengagement of the drive wheel23- with the wheel tire 7, the shaft 22 is driven to actuate the magneto, and 'tolight the lamp whenever the switch is closed. Moreover, as the wheel 64 rotates with the shaft 22, the horn may be caused to sound at will by pressing the push-button 76. .'Another important feature of the invention resides in'the simplicity of the casing structure and inthe manner of arranging the parts therein, it being observed that the circular plate 20 may be readily removed and applied without disturbing the interior parts.

I have shown the preferred embodiment of my present invention, but I do not wish to be limited to the exact details of construction shown and described, as obvious modifications thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such departures from what is herein set forth, I consider within the scope and terms of my claims.

Having thus described my invention, what I claim is:--
